RIN 2120-AA64

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to supersede Airworthiness Directive (AD) 99-16-01, 
for certain Airbus Model A300 B4-600, B4-600R, and F4-600R series 
airplanes, and Model A300 C4-605R Variant F airplanes (collectively 
called Model A300-600 series airplanes). AD 99-16-01 currently requires 
repetitive inspections of certain bolt holes where parts of the main 
landing gear (MLG) are attached to the wing rear spar, and repair if 
necessary. Since we issued AD-99-16-01, we have determined that the 
risk of cracking in the rear spar is higher than initially determined. 
This proposed AD would add airplanes to the applicability, reduce the 
compliance times and repetitive intervals for the inspections, and 
change the inspection procedures. We are proposing this AD to detect 
and correct cracking of the rear spar of the wing, which could result 
in reduced structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by January 4, 2016.

Discussion

    On July 21, 1999, we issued AD 99-16-01, Amendment 39-11236 (64 FR 
40743, July 28, 1999). AD 99-16-01 requires actions intended to address 
an unsafe condition on Airbus Model A300 B4-600, B4-600R, and F4-600R 
series airplanes, and Model A300 C4-605R Variant F airplanes 
(collectively called Model A300-600 series airplanes).
    Since we issued AD 99-16-01, Amendment 39-11236 (64 FR 40743,

[[Page 71752]]

July 28, 1999), a fleet survey and updated fatigue and damage tolerance 
analyses have shown that the threshold for the initial inspections and 
the intervals for the repetitive inspections need to be reduced.
    The European Aviation Safety Agency (EASA), which is Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2013-0180, dated August 9, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    During full-scale fatigue testing, cracks were found on the rear 
spar from certain bolt holes at the attachment of the Main Landing 
gear (MLG) forward pick-up fitting and the MLG Rib 5 aft.
    This condition, if not detected and corrected, could reduce the 
structural integrity of the aeroplane.
    DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile] 
France issued * * * [an AD] (later revised) to require High 
Frequency Eddy Current (HFEC) or Ultrasonic (U/S) inspections of 
certain fastener holes where the MLG forward pick-up fitting and MLG 
Rib 5 aft are attached to the rear spar.
    Since DGAC France * * * [issued a revised AD, which corresponded 
to FAA AD 99-16-01, Amendment 39-11236 (64 FR 40743, July 28, 1999), 
which superseded FAA AD 95-20-02, Amendment 39-9380 (60 FR 52618, 
October 10, 1995)] * * *, a fleet survey and updated Fatigue and 
Damage Tolerance analyses have been performed in order to 
substantiate the second A300-600 Extended Service Goal (ESG2) 
exercise. The results of these analyses have shown that the 
threshold and interval must be reduced to allow timely detection of 
these cracks and accomplishment of an applicable corrective action.
    For the reasons described above, this [EASA] AD retains the 
requirements of [the revised DGAC France AD], which is superseded, 
but reduces the related compliance times.

The new, reduced threshold for the initial inspection ranges between 
8,900 total flight cycles/20,000 total flight hours, and 34,600 total 
flight cycles/77,800 total flight hours, depending on the modification. 
The grace periods (750 or 1,500 landings) for airplanes that have 
exceeded the specified thresholds are unchanged from those provided in 
AD 99-16-01, Amendment 39-11236 (64 FR 40743, July 28, 1999). The new, 
reduced intervals for the repetitive inspections range between 4,000 
flight cycles/9,000 flight hours (whichever occurs first), and 8,900 
flight cycles/20,000 flight hours (whichever occurs first), depending 
on the modification. You may examine the MCAI in the AD docket on the 
Internet at http://www.regulations.gov by searching for and locating 
Docket No. FAA-2015-4813.

Clarification of Terminating Action for Certain Paragraphs

    We have determined that if the inspection in paragraph 
(g)(4)(ii)(B)(2) of the proposed AD was done it would terminate the 
repetitive inspections specified in paragraph (g)(2) of this proposed 
AD. We have revised paragraph (g)(3)(i) of this proposed AD to include 
accomplishment of the inspection in paragraph (g)(4)(ii)(B)(2) as a 
terminating action. We have also determined that if the inspection in 
paragraph (g)(4)(ii)(B)(1) of the proposed AD was done it would 
terminate the repetitive inspections specified in paragraph (g)(2) of 
this proposed AD. We have revised paragraph (g)(3)(ii) of this proposed 
AD to include accomplishment of the inspection in paragraph 
(g)(4)(ii)(B)(1) of this AD as a terminating action.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A300-57-6017, Revision 04, 
including Appendix 1, dated February 4, 2011. This service information 
describes procedures for repetitive inspections of certain bolt holes 
where parts of the MLG are attached to the wing rear spar, and repair. 
This service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section of this NPRM.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Changes to AD 99-16-01, Amendment 39-11236 (64 FR 40743, July 28, 1999)

    This proposed AD would retain all the requirements of AD 99-16-01, 
Amendment 39-11236 (64 FR 40743, July 28, 1999). Since AD 99-16-01 was 
issued, the AD format has been revised, and certain paragraphs have 
been rearranged. As a result, the corresponding paragraph identifiers 
have been redesignated in this proposed AD, as listed in the following 
table:

                      Revised Paragraph Identifiers
------------------------------------------------------------------------
    Requirement in AD 99-16-01,
 Amendment 39-11236 (64 FR 40743,     Corresponding requirement in this
          July 28, 1999)                         proposed AD
------------------------------------------------------------------------
 paragraph (a)                       paragraph (g)(1)
 paragraph (b)                       paragraph (g)(2)
 paragraph (c)                       paragraph (g)(3)
 paragraph (d)                       paragraph (g)(4)
 paragraph (e)                       paragraph (g)(5)
 paragraph (f)                       paragraph (g)(6)
------------------------------------------------------------------------

    Certain notes that appeared in AD 99-16-01, Amendment 39-11236 (64 
FR 40743, July 28, 1999), were either removed due to the revised AD 
format or converted to regulatory text in this proposed AD.
     Notes 1, 6, and 7 of AD 99-16-01 have been removed from 
this proposed AD. Due to the revised AD format, certain information in 
these notes is now included in the AD template.
     The content of Note 2 of AD 99-16-01 is regulatory in 
nature; therefore, we have included that information in paragraph 
(k)(1) of this proposed AD.
     The content of Note 3 of AD 99-16-01 has been redesignated 
as Note 1 to paragraph (g) in this proposed AD.
     The content of Note 4 of AD 99-16-01 is regulatory in 
nature; therefore, we have included that information in paragraph 
(g)(2)(ii) of this proposed AD.
     The content of Note 5 of AD 99-16-01 is regulatory in 
nature; therefore, we have included that information in paragraph 
(k)(3) of this proposed AD.

Costs of Compliance

    We estimate that this proposed AD affects 71 airplanes of U.S. 
registry.
    The actions required by AD 99-16-01, Amendment 39-11236 (64 FR 
40743, July 28, 1999), and retained in this proposed AD, take about 226 
work-hours per product, at an average labor rate of $85 per work-hour. 
Required parts cost about $0 per product. Based on these figures, the 
estimated cost of the actions that are required by AD 99-16-01 is 
$19,210 per product, per inspection cycle.
    We also estimate that it would take about 226 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Based on these figures, we 
estimate the cost of this proposed AD on U.S. operators to be 
$1,363,910, or $19,210 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.
